Incidentally just before that (6:05) watch Raymond Bennett's reaction when he's asked about the non-white members of UKIP. I think it might be his floundering over that question that makes him make his claim re Nigel Farage and Enoch Powell.
Here's the full Daily Politics interview.
Has Nigel Farage ever said that Enoch Powell is his hero? I can't find such a comment, all I did find was this interview with Dermot Murnaghan when he says that the basic principle of Enoch Powell's so called 'Rivers of Blood' speech is right.
What's especially interesting is Nigel Farage's comparison of immigration in the 1960s, 1970s and 1980s with the rate since the election of the Labour government in 1997.
